Hi Max,
Maybe the Security Settings on your internet access are set at "High".
Sometimes after I've downloaded the latest Microsoft update I find I can't access favourite websites.
Go to: Control Panel and click on the Internet Options logo.
On the top tabs choose "Security" and click.
That page is divided into three. Somewhere on that page, possibly about the middle is a panel entitled "Security Level For This Zone'
and within the panel is a slider which you can move up & down with your mouse - mine is pointed to 'Medium' and I can access most websites. I've discovered a few government sites don't have current Microsoft certification which then denies me access. You can get round this by instructing your computer to give you access.
On the same 'Security' page there is a row of icons - look for the "Trusted Sites" - mine is green with a white tick. Click on this sign.
Below those icons is the Green Internet Globe icon and alongside is the wording "Internet - these are the websites not on ...." This action should make available a button marked "Sites" - click on the button.
This action will open another page where you type in and enter the http://www… of the site you would like to access. When you've finished don't forget to click on the "Apply" button.
